T0 almohonm'tbnay concern:

Be it known that I, THOMAS SOANT'LIN, of Evansville, county of 1 Vanderbnrg and State of Indiana, have inwi ted anew and'useful Improvement in Safety Oil'- Reservoirs-oi" which "th'edollo wing is a specification:

The'object'of this invention is toprovide means for thesafekeepin'g, storing, and meas-" first, in a better inethod ofsecnring the head F of the'pumpjuthe compartment H, which compartment 'is attached toand forms apart of the capG, so that the'pum'p maybe easily taken out and replaced'when it is wanted to pump oil fromthe-cask or barrel into the res ervoir; second, of provision of 'suremethods,

by sight and touch, of ascertaining when the measuring-tubes L,'M,' and N are full.-

In'tlie accompanyingdraw'ing, Figured rep" resents avertical' sectionof the'rese'rvoir, showing its construction, taken onthe section-line a; x," with sectional views taken verticallyof internal parts of-the reservoir." Fig. 2 is a hori zontal section of Fig. 1, showing the dischargefaucets "of "the measuring-tubes, and the indicator, whose several parts are"shown'at A,

B, O, E, an dF",' and a plan view of the measuring-tubes "L,'M, and N; and the inner tubeW inthe'insideof the measuring-tube M.

Similar letters of reference indicate corre spondingparts.

A is the reservoir. B is a pumpfor'pump-V ing the oil'fr'omthe reservoir up'intoth'e head F and out 'throughthe spout J intothefilling compartment K, from whence "it flows out in- U is I the pu-mp piston'. D is *the'pi'ston-rod. E is the handle of the piston-rod. F is the head of the pump; upon theshoulder of-which head thepump'hangsin position. G is the'lid'of the reservoir. H is a compartment, with a bot tom, on top of the lid G, through which bottom, as well as through the lid G, the pump extends down into-the reservoir, The spout atelyf underneath it. und-ern'eatl1 theupper"plate S, and wedged between the plate Sand the top of the spout of the pump, coming horizontally from the head'ot the'pump,ti1rns downwardand passes through the bottom of the compartment H and on the under-side'of the lid Gr out into the filling-compartment K, from whence the fluid is'condu'cted to themeasuring-tubes. I" is-a fastener; which assists in holding the head of the pump down to its bearing on the bottoln 'of thecompartment H, through the top of which fastener-is a hole corresponding 'to' J, and -so adjusted'that-by withdrawing the pi n'sU Uthe wooden' plate may be" taken "out. It's purpos'e' there is to act "in conjunction with the fastenerI, thesoeket V, and the' pin J, in holding the head of the pump to itsplace, and permitting. it to be with drawn when the pur'npis needed foruseiu I filling the reservoir from the cask;

U U are' pins passing through"holes,perpendicularly pierced through the plates S -and T, and "so inserted as to bewithdrawn at will. 1 is a leather washer, fitted to the :hole, through which the piston-rod D passes, inthe lid L ofthecompartment H. The leather washer forms a 'stuffing-box in the'lid L for the piston, preventing evaporation of oil around the piston-rod, where it passes through said lid, and enabling the pistonrod to work without the creaking soundpe'culiartoworking'in sheet metal. B is a glassin the 'cover' of thenpper filling compartment K, through which glass may be seen the top of the wire Y, usually ornamented by being surmounted by a red star, but any plainly seen device will answer instead of the star, which rises to or near the glasses soon as themeasuri'ng tubes L and M are full. K is the lower filling coinpar'tment, its bottom being perforated with four holes, three of p which are entered by the open tops of the three'measuringtubes, so as" to communicate directly with said tubes, the fourth hole being directly over the receiver of the indicator. L, M, and N, respectively, are measuring-tubes. O, P, and Q, respectively,

' are faucets, with which to draw the fluid from the measuring-tubes when full. V is the socket in the inside of the wall of the head of forated with a small hole of the diameter of the wire Y at its upper end. This tube serves as a guide for the said wire and float to keep them in a vertical position, for the purpose of indicating by the rising of the device on the top end of the wire when the measuring-tubes L and M are full. A is a rest or fulcrum at tachedto the inner wall of the reservoir, on which fulcrum is balanced and supported, and on which freely plays, the apparatus which indicates in the dark to the retailer when all three of the measuring-tubes are full. This apparatus I term an indicator. B,.Z, E, and F are difi'erent parts of the indicator last named. The dotted lines M, M, and G indicate the space through which the indicator plays when ittilts after all three of the measuring tubes are full and run over into the receiver B of the indicator, filling that receiver and causing, it, by the accumulated weight ofthe fluid therein, to overhalance the weightof that portion of the indicator on the other side of the fulcrum. G is a guide, through which the wire E of ,theindicator passes; and this guide, attached to the wall of the reservoir, serves also as a stop to prevent. the receiver B from dropping entirely down when filled with fluid from the overflow through the hole D after the measuring-tubes are full. The hole D is in the bottom of the lower filling compartment, and immediately:

over the receiver of the indicator.

The vertically-placed wire E of the indicator plays freely up and down through the top of the hollow cone on the outside of the lid,G,-and is surmounted by the cap F ,which raises in the direction of. the dotted lines above it whenever its weight is overbalanced by filling the receiver B with fluid. The finger of the operator, being held at or about the position of G, is struck by the point of the coni031? shaped cap 13" rising upward whenever alLthree of the measuring-tubes are full of fluid, and he is thus admonished, without the of light,that all three of the tubes are Any number of tubes, each gaged to any measure,.1nay be used in like manner with my indicator.

In the bottom of the receiver B of the indicator are holes, through which the fluid leaks from said receiver back into the reservoir, after which, the receiver being relieved! of its weight of fluid, and bei1 |g, with all that part of the indicator, on the sameside ot' the fulcrum with itself, lighter than the portions of the indicator on the other side of the ful-Q crum, which have been tilted upward, the cap. F drops back to its place on the cone, and

theindicator resumes its place anduatural balance.

The mode of operation of the different parts of my invention is as follows: The oil, on being pumped, flows through'the spout J into.

the upper fillingcompartment ,K, and from thence through the single hole in that compartment into the measuring-tube L, filling that tube first. That tube being full, and the pumping continued, the fluid overflows into.

the. lower filling-compartmentK, and the mouth of the tube M (being the next tube in the row) is filled, when the float X causesthe wire Y, with a plainly seen cap on its top end, 3 l

to rise to-the glass cover R, indicating, by. looking through the glass cover, that the two. tubes L and M are full.

and raise the cap F, as before described.

As there can be no overflow from the fill-I ing-compartment into the receiverB until all three of the measuring-tubes are filled, therisq;

in g of the cap'F is a sure indication of their be-g ing full to overflowing, thus giving in properlygaged tubes an exact measurement. The, principal advantage, however, of this part of my'invention is, that it 'enablesthe retailer, that stores his 011 or other burning-fluids ina;

dark cellar or room to measure it to his yous-1 tomers without bringing a candle or burning, a light in the neighborhood of the oil or burning-fluid, which often catches fire from a burn-;

ing light at a distance. c i

The object of the inner. tubeW, wire .Y, with the star or other plainly seendeviceon 'its top, and the float X, is to enable the retailer, when he may deemit inconvenient to I use his finger over the cap 11", to ascertain, I when two of the tubes,Land M, are full ina F light too dim to tell with certainty, by looking the under surface of the glass, and thus bet I seen in a dim light notbright enough by which to discover oil at. themouths of the} tubes.
